Currently, arping from a vetp-gw physical-switch port to a VIF IP address does not work.
When a physical-switch-port arps for an IP address of a VIF, that arp packet comes into the VIF hypervisor via a vxlan tunnel. That arp packet must not be responded-to by the arp responder table. Its treatment must be similar to the arps coming in from the localnet port - which is to skip the arp responder table.
